摘要： The invention relates to a manufacturing process of equipment for use in the production of nonwoven fabrics and paper products. According to the present invention, a sleeve for an embossing roller is produced using additive manufacturing, specifically 3D printing. These technologies permit the preparation of pattern-forming and dewatering details in the sleeve in a single operation. The dewatering properties may thus be optimised for the selected pattern, resulting in uniform dewatering tailored for the pattern. Preferably, the technique used is stereolitography.

摘要： A non-woven gauze product and a method and system for manufacturing same. The spunlace device includes a second spunlace machine having a shaping layer on the surface, the shaping layer is provided with pointed projections having tapered tops disposed in a matrix arrangement, each pointed projection has a bottom of rectangular cross-section, the bottom size of each pointed projection is larger than the bottom distance between two adjacent pointed projections. A non-woven cloth having rectangular holes in an array layout is formed by water jetting the fiber-web at the second spunlace machine. The rectangular holes in an array layout are presented in a flat structure having warp and weft, and the dimension of each rectangular hole is larger than the line width of warp and weft. The features of such non-woven cloth are similar to those of gauze, so the non-woven cloth can be a substitute for the current gauze.

摘要： A method for the manufacture of spatial objects of a fleece or felt, wherein the fibers are deposited on a mold that is preferably air-permeable. The fibers may be attracted to the mold by a vacuum applied to the underside of said mold. Preferably, the mold has several spatial structures that define the shape of the fiber web that is being formed and that correspond at least approximately to the desired final shape. By subsequent compacting of the thusly obtained fiber web, a spatially three-dimensional felt object is obtained. In this method, subsequent deforming steps are unnecessary or reduced to a minimum, so that the material to be produced does not experience any substantial distortion.
